Returns a double value of specified element of array. If specified element has not PVT_Integer or PVT_Double type, nDefValue returned.

Syntax

HRESULT Arr_GetDouble([in]                     ULONG    nIndex,
                      [in, defaultvalue(0.0)]  double   nDefValue,
                      [out, retval]            double*  pVal);

Parameters

nIndex
[in] Specifies an index of the element in the array.
nDefValue
[in, defaultvalue(0)] Default value that will be returned when specified index is out of range or the element is not a boolean value.
pVal
[out, retval] Pointer to double variable that receives returned value.

Return Value

Returns S_OK if operation was successful or error code in other cases. Returns S_FALSE when nDefValue returned.
